Thailand: Weather & when to go: April

April Overview

April traditionally marks one of the hottest months of the year in Thailand, with temperatures reaching seasonal highs across the country. The high 30s are the order of the day across Thailand and humidity makes things a bit… sticky! Bangkok and central Thailand bear the brunt of the heat, which can make travel and sightseeing a bit more difficult. Rains do come now and again, but for the most part the weather stays dry… until Songkran!

While the central and northern parts of the country are baking in high temperatures, the southern part of Thailand enjoys some excellent weather. Beach goers find ideal coastal temperatures with daily averages between the high 20s to mid 30s. On the Gulf side of the south, things stay relatively dry for the month, while on the Andaman side, the occasional rains pass through Krabi, Phuket and Khao Lak, particularly during the latter half of the month. For those diving, the ideal conditions are found on the eastern (Gulf) side of the south.


April in Thailand marks the Songkran period, which is a combined New Year’s celebration and Water Festival. While the entire country enters holiday for the better part of the Songkran week, the main days of the festival are marked by giant ‘water fights’. No matter where you go, expect to be met with water guns, buckets of water and giant water hoses cooling… and soaking everyone down! This is a great way to get to know the fun-nature of the Thais, but be sure to leave the passport and smart phone at the hotel… they will get soaked!
